Efficient C++ Performance Programming Techniques

Key Points

• The global memory manager (implemented by new() and delete()) is general-purpose and consequently expensive.

• A significant boost is available if you mostly allocate memory blocks that are confined to a single thread. A single-threaded memory manager is much faster than a multithreaded one.

• If you develop a set of efficient single-threaded allocators, you can easily extend their reach into multithreaded environments by the use of templates.
